(Dual-rank 8-GB modules are supported; quad-rank 8-GB modules are not supported.) Each processor has four memory channels, organized in sets of two channels. ***If more than four memory modules are installed per processor, the memory modules will be downclocked to operate at 533 Mhz • Memory modules must be installed in pairs, beginning with the first two sockets in each set of memory modules. These sockets are marked by white retention levers • All memory modules in the blade must be identical in speed and technology. The memory modules in each pair must be the same size. If pairs of memory modules of different sizes are installed, the larger capacity memory modules must be installed in the lower numbered slots • Memory sparing is supported if 24 memory modules are installed (Memory mirroring is not supported.)
